I prefer the HSS, but if you end up w/ an SSS, wire one tone pot to the bridge, and the other to the mid/neck so you can get away from the ice pick. I also have pre-assembled pick guards as you mentioned; with HSS, HH, mini HB, EMGs, etc. If your body routing matches your pick guard choice, you can swap out your electronics on a long break!
